Did You Know?


Many parts of the body have come to have figurative meanings in English. One can have an eye for interior design, for example, or the stomach for a fight. "Muscle," of course, can mean "strength," and so can "sinew," a word for the tissue that ties muscle to bone - more commonly known as a tendon. (For a while, "sinew" also meant "nerve," but that usage is obsolete.) The use of "sinew" to mean "the chief supporting force" ties into its anatomical function as a stabilizing unit. Sinew derives via Middle English from Old English "seono"; it is also related to Old High German senawa ("sinew") and Sanskrit "syati" ("he binds").
